MB-1I-1 15A single-phase current transducer, Modbus RTU

Why choose the MB-1I-1 15A?

The MB-1I-1 15A is used to measure alternating or direct current and to transmit the reading via an RS-485 Modbus RTU network. The MB-1I-1 15A enables direct current measurement in the range 0–15 A AC / 0–20 A DC.

What does this mean in practice?

• The measurement input range is 0–15 A AC / 0–20 A DC.
• The measurement can be carried out directly within the device’s input range.
• The dedicated manual for the 15A variant also specifies compatibility with a current transformer having a secondary current of 15 A.
• For alternating current, True RMS measurement is performed.
• The result and communication parameters are available via RS-485 Modbus RTU.
• The measurement channel is galvanically isolated from the power supply and the communication interface.

Reset communication settings
A DIP switch is located on the underside of the module.
Details on resetting are available in the manual.

The software allows you to read values for testing purposes and to set the transducer’s communication and configuration parameters.
  

Communication between the module and a PC via theCN-USB-485 USB converter
The software is free of charge.
